These Wilbers springs have a 4.0 N/mm to 6.0 N/mm two stage rate compared to the linear 4.0  N/mm stock springs. This two stage progressive philosophy works really well in long travel forks such as on the DR650.The first rate rides very nicely over the small bumps providing good comfort, but then they ramp up in rate controlling weight transfer and nosedive under heavy braking, and add bottom out resistance when the terrain gets more challenging. 

Don't forget the Fork Oil!  You will need 2 Liter of 7wt or 10wt for these springs.

Please note:

7wt oil is recommended for general purpose and for more dirt road riding.

10wt oil is recommended for sport-oriented street riding.

Air chamber is 160mm with springs removed and forks completely compressed.


Instructions for setting air chamber: 

 

1) Remove fork spring and drain old oil. 

2) Compress fork fully with spring removed.
3)  Add oil until oil level is the prescribed distance from the top of the tube - this is your air chamber.
Piston rods should be pumped several times to dispel any remaining air before final measurement is made.
